A plant operates under steady-state conditions. Sea water enters the plant with a mass flow rate of 1000 kg/hr and a density of 1030 kg/m³. Brine (i.e., a high- concentration solution of salt in water) exits at 150 kg/hr with a density of 1250 kg/m³. Water vapor also exits the plant at a pressure of 125 kPa and a temperature of 115°C. The water vapor can be modeled as an ideal gas with Rvapor = 461 J/(kg-K). 1 Seawater

b) A 3 cm orifice plate is placed within a 4 cm pipe in which methanol at 20 °C (SG = 0.7884 and dynamic viscosity (µ) = 0.5857 cP) is flowing through. If the flow rate passing through the pipe is 3.1 litres per seconds, determine the pressure difference that must be measured around the orifice plate. The discharge coefficient of the orifice can be calculated by: 91.71B2.5 Ca = 0.5959 + 0.0312B2.1 – 0.184ß® + Re0.75 Where, B is the ratio of orifice diameter to pipe diameter and Re is the Reynolds number.

Hydraulic motor calculations Theoretical flow = 1.5 GPMRPM output = 100 RPMMechanical power = 0.25 HP Total efficiency = 85%Volumetric efficiency = 92%   a) Calculate the theoretical engine displacement (in3/r). b) Calculate the actual engine flow in GPM. c) Calculate the actual torque (lb.in).

a) A suction pump. Consider a pipe that is inserted vertically into water. By suction, the pipe is evacuated of air. How high will the water rise? b) A water turbine is designed to extract kinetic energy from the hor- izontal flow of water and convert it into rotation of the turbine. You may assume that the height of the fluid does not change as it flows through the turbine, and that the fluid is incompressible. If the velocity is lowered from 100 m/s to 70 m/s as the fluid flows through the turbine, what is the change in pressure? c) Is the pressure higher upstream or downstream? d) The fluid in (b) is replaced by air to make a wind turbine. What is the change in pressure now for the identical change in velocity to (b)?

Please explain all intermediate steps. Thanks you

A new type of energy absorber is being designed as a buffer at the end of track at a fairground.It consists of a piston with small holes that moves in a cylinder containing oil, so that the kineticenergy of impact is absorbed as heat by the oil.a) Draw a sketch for the instant of impact by a vehicle of mass 2500kg moving at 30mphshowing the forces and energy transfers involved.b) Write down the first law of thermodynamics for a system and identify terms that are notrelevant if the oil is taken as the system.c) How much heat transfer to the surroundings is required to return the oil to its originaltemperature after an impact by a 2500kg vehicle moving at 30mph?

A pipe has a cross-sectional area of 16.5cm2 at point A, where the speed of the fluid (water) is 1.2 m/s and the pressure is 2.00 atm. The pipe ascends 3.00 m and narrows to 8.20 cm2 at point C. a) what's the speed of the fluid at point C. b) what's the absolute pressure at point C.
